HAT-P-42b and HAT-P-43b. Two Inflated Transiting Hot Jupiters from the HATNet Survey
I. Boisse, J. Hartman, G. Bakos +20
First identified from the HATNet wide-field photometric survey, these candidate transiting planets were then followed-up with a variety of photometric observations. Determining the…
Three Tests of LambdaCDM
C. J. A. P. Martins
The observational evidence for the acceleration of the universe demonstrates that canonical theories of gravitation and particle physics are incomplete, if not incorrect. A new gen…
Shades of Hyperbolicity for Hamiltonians
M. Bessa, J. Rocha, M. J. Torres
We prove that a C2 Hamiltonian system H in M is globally hyperbolic if any of the following statements holds: H is robustly topologically stable; H is stably shadowable; H is stabl…
On periodic points of free inverse monoid endomorphisms
Emanuele Rodaro, Pedro V. Silva
It is proved that the periodic point submonoid of a free inverse monoid endomorphism is always finitely generated. Using Chomsky's hierarchy of languages, we prove that the fixed p…
Probing unification scenarios with atomic clocks
M. C. Ferreira, M. D. Julião, C. J. A. P. Martins +1
We discuss the usage of measurements of the stability of nature's fundamental constants coming from comparisons between atomic clocks as a means to constrain coupled variations of…
Planck Intermediate Results. XI: The gas content of dark matter halos: the Sunyaev-Zeldovich-stellar mass relation for locally brightest galaxies
Planck Collaboration, P. A. R. Ade, N. Aghanim +194
We present the scaling relation between Sunyaev-Zeldovich (SZ) signal and stellar mass for almost 260,000 locally brightest galaxies (LBGs) selected from the Sloan Digital Sky Surv…
